The trainers load the game in the same way (there may be minor differences) so maybe try updating your Flash Player on IE?
If not, just use an earlier version of Le Bot with the feature: https://www.mpgh.net/forum/showthread.php?t=756050
Remember that the load shop feature was disabled on purpose in recent Le Bot versions - you're supposedly in danger of a ban if you use it in some areas (only rumoured), but the feature hardly has any use anymore.
